HARTMANN TRESORE AG is a modern company, accrued from long-standing handicraft tradition. More than 150 years ago, the 'blacksmith and cartwright company Hartmann' has been founded in Westphalia. We are proud of the today's steel- frame building facility being still in family ownership. In 1983, Christoph and Heinrich Hartmann founded the company HARTMANN TRESORE, a company meeting the challenges of a long-standing tradition.
